same thing

o yeah probably should have shown that aswell

thanks guys makes much more sense i was trying to use the fact that cos2x = 2cos^2x-1 it got pretty messy

i think you just say PS^2= a^2(p^4+2p^2+1) =a^2(p^2+1)^2 therefore PS=a(p^2+1)

hey can someone help me with this question please? its probably alot easier than i think it is but yeah.. π/6 ∫ sin4xcos2xdx -π/6 thanks for your help

yeah this doesnt invole any integration. y=sqr(4-x^2) is a semi circle of radius 2 but x-y+2=0 is intersects with the semi circle at x=0 and x=-2 so what you actually want to do, is find the area of the quarter circle, and the area of the triangle made by x-y+2=0 and the x axis and y...

well it shouldnt really effect the answer. but yeah the books wrong

good work, 4 unit is the best. its so much more interesting than shitty mathematics

I only have 2 at my school. i like the small clas much better because we dont have to wait for other people so we can go through the course at a fair pace you thinkin of doin 4 unit Kurt?

i reckon yanny's ways the right way id do it 2 X 5!=240 as there are only 2 ppl that can sit in the front drivers and when one person is sitting in the front seat, theres 5! ways the other ppl can sit

I reckon you should be doin 2 unit revision if theres the chance that you may drop 4 unit.

4 unit maths 8.5 3 unit maths 8 2 unit maths 5 Chemistry 7 Physics 5 Advanced eng 6 Japanese 3

So who went to his show at centennial how good was it!!! i love him and isnt g love the epitome of cool?

sorry its pretty messy EDIT: there we go, thats a bit better, never have bin good with neatness

ok here we go: step 1: prove n=1 LHS = 2/3 RHS = 1 - 1/3 = 2/3 Therefore the statement is true for n = 1 step 2: assume true for n=k 2/(1X3)+2/(3X5) + ... + 2/(2k-1)(2k+1) = 1 - 1/(2k+1) step 3: rtp n = k+1 2/(2k-1)(2k+1) + 2/(2k+1)(2k+3) = 1-...

is it for all n=>1 coz n=1 isnt working for me? its for all n=>2 yeah? actually i agree with cwag not sure u got the question right there mate

7 hours a week! wish i had that much we'd be like finished at the rate we're goin. we've only got 2 ppl in our year and what u mean uve done trig? thats not a 4 unit topic is it?

yeah its does, doesnt it? works for me anyway.
